Re: [Mingw-cross-env-list] linking to libboost_thread_win32-mt.a

Ok got it going. I had to add #define BOOST_THREAD_USE_LIB to the top of my source code and it compiled. when I ran it in wine there were other errors but that another thing. thanks for all your help.

Thanks for the reply.
I changed LIBS to LIBS="$LIBS -lboost_thread_win32-mt"
And am now receiving the error:
terminal.o: In function `thread<int (SshClient::*)(int), SshClient*, int>':
/home/deadpickle/mxe/usr/lib/gcc/i686-pc-mingw32/4.7.0/../../../../i686-pc-mingw32/include/boost/thread/detail/thread.hpp:259: undefined reference to `_imp___ZN5boost6thread12start_threadEv'
terminal.o: In function `ZN10MainWindow12get_stn_infoEv':
/home/deadpickle/hprcc_terminal/src/terminal.cpp:35: undefined reference to `_imp___ZN5boost6threadD1Ev'
I received this before and assumed that it was because I was linking incorrectly. How can we fix it?

       I'm trying to use the boost_thread libraries in my program and
       are having troubles linking to the library. Im using autotools
       to build my project and I keep getting the error
       /home/deadpickle/mxe/usr/lib/gcc/i686-pc-mingw32/4.7.0/../../../../i686-pc-mingw32/bin/ld:
       cannot find -lboost_thread_win32-mt.a
       So far I have tried setting the LDFLAG in my configure call
       and specifying -llibboost_thread_win32-mt.a and none of these
       seem to be working. Any ideas?

   The flag "-lboost_thread_win32-mt" corresponds to the file
   "usr/i686-pc-mingw32/lib/libboost_thread_win32-mt.a". In other
   words, in your linker flag, omit the "lib" prefix and the ".a" suffix.

hope im understanding your reply correctly.

in configure.ac <http://configure.ac> i removed the -l and a.

LIBS="$LIBS libboost_thread_win32-mt"
then ran
./configure --prefix=/home/deadpickle/hprcc_terminal/win32 --host=i686-pc-mingw32 LDFLAGS='-L/home/deadpickle/mxe/usr/i686-pc-mingw32/lib/'
but still received the error
i686-pc-mingw32-g++: error: libboost_thread_win32-mt: No such file or directory

Don't omit the "-l" flag. Do omit the "lib" prefix and the ".a" suffix.
